Trouble viewing event history on mobile via Ring app

Hi guysRecently started having issues viewing event history via my Samsung S9. Videos hang and take forever to load when connected on my home wifi (same network as the door bell and 3 spot light cameras). However when on mobile data videos load in just fine.Signal strength on all cameras are very good and there does not seem to be any connection issues with my phone to our network.There are no issues with Live view on either wifi or mobile date. My wife is also having the same issues on her Samsung S9.Any ideas?Cheers
